Family discovers doorstop is really meteorite

4-billion-year-old rock found in Kentucky cow pasture in 1930s

A Tennessee family recently discovered that their doorstop was, really, out of this world.

Scientists confirmed that the 33-pound, oval rock is actually a 4-billion-year-old meteorite that likely fell to Earth during a meteorite strike in 1853, the Lexington Herald-Leader reported.

Donna Lewis told Fox News her grandfather picked the meteorite out of a cow pasture in Kentucky in the 1930s.

It's served as a door stop through the years and was even painted green and used as decoration in a flower bed at one time.

Lewis and her husband, George, took the rock in for testing after running a metal detector over it in May. To George Lewis' surprise, the detector's dial registered "overload," according to the Herald-Leader.

After confirming its meteorite status, Eastern Kentucky University purchased the rock for eventual display.
